True or False: Is an Apache error or PHP error the same as a WordPress error?

WordPress errors are application level errors. PHP errors are language syntax or usage errors and appach error are errors detected during the web server operation.

Errors, especially minor ones, might be reported “upwards” and look like they are wordpress application errors, or logged downwards and be part of the apache server error log if the applications wants it. In the end of the day, where they are reported is less relevant, the error itself is what matters.
